Sin Signet Spiker Edit

Hello,
I was looking at the http://www.pvxwiki.com/wiki/Build:A/E_Signet_Spiker build. I realize that it dosn't provide enough energy and personally the blinding skill is a waste of other great skills. I was thinking to replace Blinding Surge with Ash blast which would follow entangling asp. To replace Deadly Paradox and Feigned Neutrality would be Assassins promise (Energy management) and an Optional slot. With 16 Deadly Arts this would PWN (IMO). Thoughts? Comments? Thanks.

It's an old build, and I've seen Ash Blast been used. I prefer the Augury of Death signet spiker though.

Can you explain that build? Anyone else have comments? This will be the sole reason for me to bother making a sin.

If I remember, that build was originally designed shortly after NF release when bsurge was 5e as a split character in gvg. I think the augury of death build today is something like, deadly paradox->augury->dancing daggers->entangling asp->signet of toxic shock, feigned neutrality, rez, then whatever you want for the last slot.

Crippling Dagger?
